ATTACHMENT. FOR (ZONING MACHINES;

Application filed February'23'; 1987. Serialflo: 170:130.

My invention relates-to coningmachinea and more particularly to' anattachment which will enable several concentric turnsof yarn to. bewound on the base of a spindle before the spindle is filled inthe'usual'manner.

In using yarn fromconesfor' the manufacture of certain goods, it isadvantageous to tie the inner end of'the yarn on one, cone to the outerend' of'theya'rn-on another: cone so that no delay will, be caused when:the yarn on the first cone has been exhausted. As yarn isordinarilywound spirally on cones, it, follows that it cannot be unwound from theinner end. In filling cones for" this purpose, it is customary to leavean end hanging free from the base of the cone but it is impractical toleave a: very long end and; in handling, this end is often broken ofilThe object of'my invention is to provide means whereby a standard coningmachine will-be adapted to make a number ofconcentricturns of yarn onthe base of acone before commencing to wind the yarn spirally thereon.

This object, and other advantageousend s which will be describedhereinafter, I" attain in the. following manner, had. to theaccompanying drawingstin which I have illustrated, my device as being"attached to a standard coning machine, such as is manufactured by theFoster Machine Company of Westfield, Mass, and have shown only; suchparts of the-machineasis necessary to illustrate how my attachment ismounted and used;

Figure 1 being a fragmentary cross sectional view through a coningmachine on which my attachment is mounted,

Figure 2 a fragmentary front view of certain parts shown in Figure 1 andshowing several concentric turns of yarn on the base of a cone and theyarn being led from the attachment to start the spiral winding.

Figure 3 is an enlarged view somewhat similar to Figure 2 but showingthe yarn held in position for making the concentric turns on the cone,and

Figure 4 an edge view thereof.

Figure 5 is an enlarged plan view, and

Figure 6 an edge view of my attachment.

Figure 7 is a view of a cone on which several concentric turns of yarnhave been made and showing the yarn starting its spiral path about thecone.

reference being Referring now more particularly to Fig-' ure 1,IOrepresents a gear fixed on' themam shaft 11 of mooning-{machine and itis meohanically' connected" to-a trip 12 mounted on aroclrshaft13 I bymeans not shown; A drop wire 14, having a-hookpart 15 and journalledonastop motion 1'6, issupported by the yarn=being wound onthe cone and isadapted to fall when the yarn breaks and allow hook part 15 -tobeengaged by trip 12; As-trip1 2 is-rocking on shaft 13, itwill f'orce=part 15 -forwardly and cause thelower part. of the rockerstop motion--16" to move forwardly and" engage a: rack 17 which is hinged to aconnecting-rod lS: A cone holdor 19 isrigidly connected to theupper endof connecting rod 18 and carries a: cone 20 which is-rotatedbycontacting'witlra roller 21 rotated by ashaft 22. Thus when=rack 17 ismoved fonwardly by stop motion. 16, cone 20 will be moved out of contactwith roller 21 and cease to rotate. Yarn is wound onto cone- 20 from-acop' 23, mounted on a lower portion'of' the machinqby lead ingthe yarnthrough: a= tension device 24, under drop wire 14' and over: a threadbar 25. Thepartsthus-far described are parts of a-standardconinggmachine and form no part of'my invention but have beenillustrated'and-desoribed in=order that the'location a-nd useof-iny-invention may be undenstood.

Threadbar 25is mounted in suitable sockets formed inithe'upper part ofstopmotion 16" and held' in place.- by set screws- 26; My attachment 2Tconsists of a: thin plate, formed as shown in Figure 5, and having aslot 28 adapted to straddle one of the set screws 26 and is held inplace on stop motion 16 by a nut 29 threaded on the set screw.

Attachment 27 is provided with an irregular shaped opening 30 and atongue 31 and is secured to stop motion 16 with the top of tongue 31level with the top of thread bar 25 and with the lower end of opening 30disposed parallel with the vertical side of thread bar 25 so as toprovide a guideway 32 for the yarn at this point, as shown in Figure 3.Above opening 30, attachment 27 is provided with a curved extension 33which is adapted to guide the yarn onto thread bar 25 when it is whippedout of guideway 32 by the thread guide (not shown).

Opening 30 extends downwardly and inwardly from the end of tongue 31 toform guideway 32, as above described, and extends upwardly and inwardlyfrom the end of extension '83 to provide a space into which the yarn maywhip when it first feels the impulse of the thread guide, thus tendingto prevent the yarn from breaking. The outline of attachment 27 may beas desired but the location and outline of opening 30 is important andshould be as shown in Fig ure 5. l V t e In winding cones for thepurpose above described, the end of the thread is engaged in a notch 34,formed in the bottom ot cone 20, the cone placed on holder 19 and theyarn led through guideway 32. Rack 17 is then moved inwardly to bringcone 20 in contact with roller 21 which is revolving at a high speed andconsequently causes cone 20 torotate rapidly and wind a number ofconcentric turns around its base, as shown in Figures 2 and 7. Thethread guide is then thrown into operation and the yarn whipped out ofguideway 32 by the action of the thread guide and deflected onto threadbar 25 by extension 33. Figure 2 shows the any delay thread as itisabout to leave opening 3O and Figure 7 shows approximately-thebeginning of its spiral path around cone 20. The cone is then filled inthe ordinary manner. I

In using the filled cone, the yarn is disengaged tromnotch s4 and asmuch .yarn unwound from the concentric winding as may be desired. It isthen tied to the outer end of the yarn on another cone and, in thismanner, the yarn on as many cones as desired may be joined together andthus avoid due to the changing or cones.

While I have described my invention as taking a particular form, it willbe understood that modifications may be made with out departing from thespirit thereof, and hence I do not limit myself to the preciseconstruction set forth, but consider that I am at liberty to make suchchanges and al.-

terations' as fairly come within the scope of: the appended claims; v

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a machine adapted to wind yarnspirally upon a cone and having a stop motion, a yarn guiding attachmentmounted on the stop motion and adapted to guide a number of concentricturns of yarn upon the cone.

2. In a machine adapted to wind yarn spirally upon a cone'and having astop motion, an attachment mounted on the stop motion, and a guidewayformed in the attachment for guiding a number of concentric turns ofyarn upon the cone.

8. In-a machine adapted to wind yarn spirally upon a cone and having astop motion and a thread bar, a yarn guiding attachment mounted on thestop motion, a guideway formed in the attachment for guiding a number ofconcentric turns of yarn upon the cone, and an extension on theattachment for deflecting the yarn onto the thread bar when the spiralwinding begins.

LIn a machine adapted to wind yarn spirally upon a cone and having astop motion, a thread guide and a thread bar; a yarn guiding attachmentmounted on the stop motion and having an opening; a guideway formed inthe attachment-for guiding a number of concentric turns of yarn upon thecone; and an extension on the attachment for deflecting the yarn ontothe thread bar when the spiral winding begins; the top of the openingextending above the bottom of. the extension to form a relief space toreceive the yarn when it is whipped out of the guideway by the action ofthe thread guide.

In testimony whereof I have signed my name to this specification.
